AbstractPurpose: To evaluate the clinical behavior of a compomer restorative system, Dyract AP, placed in combination with Non-Rinse Conditioner and Prime&Bond NT in permanent posterior teeth. Materials and Methods: Fifty Class II and 41 Class I restorations were placed in 39 patients in a dental teaching hospital. The restorations were evaluated directly at baseline and after 6, 12 and 24 months using the modified USPHS-Ryge criteria. Clinical photographs, polyvinylsiloxane impressions and bitewing radiographs of each restoration were taken for indirect assessment. Results: After 2 years, all 76 restorations were evaluated in situ. Color matching ability and surface characteristics were excellent. A gradual deterioration in marginal discoloration and marginal integrity was noted. The percentages of Alfa scores for each criterion at the 24-month evaluation were: color match 96%, marginal discoloration 50%, marginal integrity 26%, anatomic form 97% and surface texture 95%. Five of the restorations (6%) had experienced partial fracture or recurrent caries. After 6, 12 and 24 months, the net mean occlusal wear values were 18.5 μm, 35.7 μm and 55.9 μm, respectively. There was no statistically significant difference between Class I and II restorations for each criterion (Fisher's exact test, P> 0.05).
